Any Android Market API from Google?

Not sure if its a possible duplicate. If so please merge to the appropriate.

I am looking for Google Market API that can pull the following information:

1. List of categories (in Apps, Books, Movies) in the Google Market
2. List of Top free apps/books/movies (by no. of downloads, ratings etc.) in a given category.
3. List of Top Paid apps/books/movies (by no. of downloads, ratings etc.) in a given category.

Is there an official Google Market API available?

I came across the below project but the feature set it provides doesn't support this functionality. http://code.google.com/p/android-market-api/

Any help is highly appreciated.
